OEE Quality Rate

Quality rate is one of three elements of Overall Equipment Effectiveness (OEE), a Total Productive Maintenance (TPM) measure of how effectively equipment is used. It expresses losses due to scrap and rework as a percentage of total parts run. OEE multiplies availability, performance, and quality rates.

Study notes

OEE = Availability Rate × Performance Rate × Quality Rate.
Example: 0.90 × 0.95 × 0.99 = 84.6% OEE.
OEE typically focuses on six major losses: failures, adjustments, minor stoppages, reduced operating speeds, scrap, and rework.
Some companies add other measures judged important to their business.
